I'm driving myself nuts here! Going round in circles in my brain!
Paid last week as I always pay on last weekday of month to keep straight as my payment due day is 2nd of month
But statement dates are 7th of the month
At time of paying I followed my usual routine of selecting from the list of options on the payment page to pay off the statement in full - in order to avoid incurring interest and so I clicked the "last statement balance" option
Paid the amount listed there and it's showing as accepted on my account
So in theory that's a zero balance yes?
Then I still have transactions for things I have bought from 6 Oct onwards showing as still...active?
So are they the transactions I'll pay for in the statement dated 7 nov? And my account is up to date? As in no interest?
Im so confused and annoyed at myself that I cannot remember if this is how it usually looks at this point in the month.
So
7 Oct statement lists transactions up to 7 Oct and the statement balance is what I just paid
7 Sep statement lists payment made by 2 aug, and transactions from 8 aug to 6 Sep
So...7 nov statement - my next payment? Is for transactions from 8 Oct to 7 nov but I don't pay it until 2 Dec? Is that right?
This is keeping me up and they're not open until 7 am
It's driving me bonkers!
Somebody reassure me I've not incurred interest so I can sleep? 
I really struggle with understanding this kinda thing!
